Selective Catalytic Reduction Device SCR - catalytic converter

A Selective Catalytic Reduction (SRC) device or a catalytic converter is often associated with a muffler in a reciprocating internal combustion engine (heat engine) exhaust line, particularly if it comes to a power plant with a high capacity, therefore with significant fumes flow rates.

In some cases, it comes to the inserton of a cartridge, requiring for the silencer a removable part, to allow its possible replacement.

In other cases, the catalyst is dissociated, constituting an independent subset.

Selective Catalytic Reduction (SCR) is a technique for treating exhaust gases i.e. with combustion products such as coal, oil, gas.

It mainly involves reducing nitrogen oxide (NOx) emissions, typically at a concentration of less than 250 mg / Nm3, by performing a chemical transformation (oxidation-reduction) towards compounds such as nitrogen (N2) and water (H2O).

A catalytic converter limits the release to the atmosphere of toxic elements such as hydrocarbons, carbon monoxide (CO), typically at a concentration of less than 650 mg / Nm3, and nitrogen oxides by means of a specific chemical reaction.

A consulting and trade represention office specialized in acoustics based near Lyon (France)

+

ITS is a consulting and trade representation office specialized in acoustics based near Lyon (France, Rhône Alpes area) whose range is national and can extend to neighboring countries.

Its activity is related to the design, supply and if necessary the installation of soundproofing equipment in the context of prevention or reduction actions of noise nuisances, by the means of a personalized approach of supporting of customers (which does not replace that of project managers, control offices or architects with the contracting authority).

The core business of ITS is including (in addition to on site acoustic measurements if required), as a mean but not as a finality: consulting and engineering activities as acoustical consultant office oriented toward construction technologies (selection of insulation materials and of insulating construction systems, sizing of soundproofing equipment by the means of predictive acoustic software that has mostly been developed by ITS human resource, being based on Research & Development jobs).

ITS provides solutions of fight against noise carefully designed, diverse, optimized with respect to the challenges of each project, with a quality implementation, environment friendly, in accordance with the rules of the Art as performed by specialists in the dependency of which is the application.

Acoustic insulation materials (including: for industrial or tertiary buildings), industrial and environmental soundproofing equipment (including: devices for the reduction of machinery noise and for the reduction of heat, cold or electricity production facilities, road and railway traffic noise limitation devices, products for reducing the reverberation of premises, silencers for all applications ...) and equipment for acoustic testing rooms: all equipment (standard or custom) that one can source through ITS with a guaranty of acoustical performance.

ITS acts to make possible choice soundscapes everywhere: protection of workers against noise, preservation of sound environment, limitation of noise emissions in the energy sector, testing room acoustics, acoustic comfort in buildings. Auditory trauma due to noise exposure (most often: from machinery and from industrial noisy equipment namely at workplace), what is a frequent professional risk,are thus avoided namely by the means of industrial soundproofing equipment such as acoustic enclosures (i.e. soundproofed hoods = housings) of machines, fencings, noise barriers and silencers of all types in production workshops and in other workplaces or by the implementation of cabins protecting people like operators.

The problems associated with insufficiency of sound insulation in constructions of all types (inadequacy of sound attenuation of partitions, acoustic insulation fault, faults generating unwanted transmissions of airborne sound or of impact noise ...) are also treated as well as the propagation of equipment noise inside buildings. The acoustic discomfort associated with reverberation (lack of sound absorption, insufficient spatial sound decrease) of industrial or tertiary premises (among them open spaces offices, sports facilities like swimming pools, ice rinks ..., meeting rooms, polyvalent premises and restaurants), and also other nuisances related to architectural acoustics are also cured as well as the neighborhood trouble related to noise emissions generating a rise above the permissible limit in the environment of industrial sites or near infrastructures of transport by road or rail. As soon as they are built, too noisy equipment (i.e. likely to generate noise pollution) can be equipped with soundproofing materials that can incorporate in case of need related technical features (finishing work). ITS also operates with respect to the realization of premises for which a special acoustic performance is required (soundproofed test benches & test rigs, acoustic measurements rooms - like anechoic rooms, reverberant rooms, aeroacoustic wind tunnels - , listening rooms (for test jury), auditoriums, ... and all types of soundproofed premises).

Whether for constrction projects or refurbishments, products and services offered by ITS are destined for manufacturers (OEM), installers or end users having a project (sometimes subject to constraints legislation or regulations) in relation to sound insulation (in the common language: phonic) for which solutions which guarantee the effectiveness (because tried),compatible with the other issues, sustainable and economically viable are sought.
